WASHINGTON -- The Window and Door Manufacturers Association (WDMA) said it has filed a brief with the U.S. Supreme Court urging it to hear an appeal filed by window and door manufacturer Pella Corporation of Pella, IA, over a class action case involving one of its window products.

The Pella appeal challenges a decision made earlier by the U.S. Seventh Circuit Court in the case of Pella Corporation v. Saltzman that would  loosen the criteria that must be met before a court can grant class action status based on an alleged product defect.

WDMA filed the amicus brief along with the National Association of Home Builders, National Association of Manufacturers and the U.S. Chamber of Commerce, arguing the Seventh Circuit decision disregards that bar and paves the way for unjustified class action lawsuits to be launched against manufacturers.
